Rotor of wound rotate synchronous motor

Abstract

A rotor of a WRSM motor is provided. The rotor of the WRSM motor includes a rotor body that has a rotary shaft joined to the center thereof and wound with a rotor coil and a slip ring module that is installed on an end of the rotary shaft to slidably move in an axial direction of the rotary shaft and that is electrically connected with a connection end of the rotary coil. A pair of first connectors is installed in the slip ring module to protrude toward the rotary body and a pair of second connectors is installed to connect the rotor body and the connection end of the rotor coil and is connected with the first connectors by a female and male connection method.

 a rotor body having a rotary shaft joined to the center thereof and wound with a rotor coil;   a slip ring module installed on an end of the rotary shaft to slidably move in an axial direction of the rotary shaft and electrically connected with a connection end of the rotor coil;   a pair of first connectors installed in the slip ring module to protrude toward the rotary body; and   a pair of second connectors installed to connect the rotor body and the connection end of the rotor coil and connected with the first connectors by a female and male connection method.   
     
     
         2 . The rotor of  claim 1 , wherein the first connector includes a terminal pin as a conductive plate having a predetermined width and a predetermined thickness and is conductible. 
     
     
         3 . The rotor of  claim 2 , wherein the second connector includes a connector body into which the terminal pin is inserted and electrically connected with the terminal pin. 
     
     
         4 . The rotor of  claim 3 , wherein the connector body is a conductive plate having a predetermined width and bent to receive the terminal pin. 
     
     
         5 . The rotor of  claim 3 , wherein a guide rail is formed on the outer periphery of the rotary shaft in the axial direction. 
     
     
         6 . The rotor of  claim 3 , wherein the connector body includes a connection terminal into which the terminal pin is inserted, and round shaped convex portions of the connection terminals are provided to contact while facing each other and elastically deformed by the terminal pin. 
     
     
         7 . The rotor of  claim 3 , wherein the terminal pin includes a connection end curved in an oval shape. 
     
     
         8 . The rotor of  claim 7 , wherein the connector body includes the connection terminal into which the terminal pin is inserted, and portions of the connection terminals, which face each other are spaced apart from each other in a “ ” shape and elastically deformed by the connection end. 
     
     
         9 . A rotor of a wound rotate synchronous motor (WRSM), comprising:
 a rotor body having a rotary shaft joined to the center thereof and wound with a rotor coil; and   a slip ring module installed on an end of the rotary shaft to slidably move in an axial direction of the rotary shaft and electrically connected with a connection end of the rotor coil,   wherein the slip ring module includes:
 a brush contact portion that contacts a brush and a ring type terminal mounting portion connected with the brush contact portion, 
 a pair of first connectors installed in the terminal mounting portion to protrude toward the rotor body, and 
 a pair of second connectors connected with the first connectors by a female and male connection method and installed in the rotor body to be connected with the connection end of the rotor coil. 
   
     
     
         10 . The rotor of  claim 9 , wherein the first connector includes a terminal pin as a conductive plate having a predetermined width and a predetermined thickness and is conductible. 
     
     
         11 . The rotor of  claim 10 , wherein the second connector includes a connector body installed in a bobbin of the rotor body, connected with the connection end of the rotor coil, and electrically connected with the terminal pin. 
     
     
         12 . The rotor of  claim 11 , wherein the connector body is a conductive plate having a predetermined width and bent to receive the terminal pin. 
     
     
         13 . The rotor of  claim 12 , wherein the connector body includes the connection terminal into which the terminal pin is inserted, and the connection terminal is elastically deformed by the terminal pin. 
     
     
         14 . The rotor of  claim 11 , wherein the connector body includes the connection terminal into which the terminal pin is inserted, and round shaped convex portions of the connection terminals are provided to contact while facing each other and elastically deformed by the terminal pin. 
     
     
         15 . The rotor of  claim 11 , wherein the terminal pin includes a connection end curved in an oval shape, the connector body includes the connection terminal into which the terminal pin is inserted, and, portions of the connection terminals, which face each other are spaced apart from each other in a “ ” shape and elastically deformed by the connection end.
